# Are you Out There

Here we go! First Up - We are going to talk about Check Digits and Security with a little MOD Math and programming on top for added good fun. You need to watch a little, write a little, learn a little, take a quiz a little and then move on.. I promise you that if you do it in the order I laid it out your life will easy!
